DRIVING-BOX FOB LOCOMOTIVES.

Application filed April 22, 1916.

To all whom it may concern:

Be it known that I, ALBERT A. JUNKER, a citizen of the United States,residing at Bufialo, in the county of Erie and State of New York, haveinvented new and useful Improvements in Driving-Boxes for Locomotives,of which the following is a specification.

This invention relates to the wear plates or so-called liners used onthe journal or driving boxes of locomotives, trucks and trailers andadapted to take up the lateral or lost motion between said boxes and thewheels.

- It is the object of this invention to so construct the wear plate orliner that it will eliminate entirely the necessitv of dropping orremoving the axle and wheels from the box in repairing or renewing theliner.

A further object is to improve such wear plates with a view of securinggreater economy and ready application and renewal thereof. I i

In the accompanying drawings: Figure 1 is a front or outside view of alocomotive driving box equipped with my improved liner. Fig. 2 is a rearview thereof. Fig. 3 is a vertical section on line 3-3, Fig. 1. Fig. 4is a horizontal section on line 4-4, Fig. 3. Fig. 5 is a perspectiveview of a segment of the liner.

Similar characters of reference indicate corresponding parts throughoutthe several views.

The driving box equipped with my improved liner is similar to thoseordinarily employed in connection with the axles and wheels oflocomotives, trucks, trailers and the like, except as hereinafterdescribed. As shown in the drawings, the box comprises a body 1, havingthe usual opening for receiving the axle 2 on which the wheel 3, shownby dotted lines, is mounted. 4 is the usual brass or bearing pieceresting on the axle, and 5 the customary lubricating cellar, normallyoccupying the space below the axle. As is customary in driving boxes ofthis character, the cellar is removably secured between the downwardextensions 6 of said box by means of bolts or pins 7.

Removably secured to the front or outer face of the driving box is myimproved wear plate or liner, which preferably consists of a pluralityof curved plates or seg ments 8 made of steel, bronze, brass or otherappropriate material, the joints of which Specification of LettersPatent.

are shown at 9. Any suitable means may be employed foi removablysecuring this segmental liner to the '(lriving box, but the preferredconstruction is that shown in the drawings. The outer face of the box isprovided with a dove-tailed arcuale groove or guideway 10 which iscurved substantially concentrically with the axle and extends to theopening in the bottom of the driving box in which the cellar is located.The liner is provided on its inner face with correspondingly dovetailedtenons or projections 11 which slidably fit in said groove and areadapted to slide circumferentially therein to permit their insertion andremoval. The liner illustrated in the drawings is composed of foursegments or sections but may be made of a greater or less number ifdesired. These segments are tightly'held in place in the companiongroove by means of two dovetail keys or holding plates 12 adapted toengage correspondingly dovetailed grooves or key ways 13 arranged onopposite sides of the bottonropening of the driving box. Each of thesekeys is held securely in place by means of a clamping bolt, 14 passingthrough a flange or ear 15 at the inner end of the key and threaded intoan opening in the adjacent portion of the box-body. The opposite end ofeach key is beveled or chamfered, as shown at 16, while the opposinginner edges of the two lowern'iost sections 8 of the liner arecorrespondingly beveled, as shown at 17, so that upon driving the keyshome and tightening the bolts 14, the lowermost sections are wedgedagainst the contiguous segments of the liner, thereby firmly and tightlyholding them in place in the groove 10, and also preventing theirvertical displacement therein; By this manner of retaining the segmentalliner in place, any possibility of vibration is avoided.

After the liner is assembled, the outer face thereof. may be coveredwith a layer of Babbitt metal, not showrrin the drawings, the object ofwhich is to pi event undue friction and wear between the hub of thewheel and the face of the liner.

When it becomes necessary to remove the liner for repairs or renewal,the lubricating cellar is removed by withdrawing the pins 7, releasingthe keys 12 and withdrawing them out of the path of the liner segments.The latter are then removed downwardly through the bottom-opening of thebox-body in an obvious manner, thus avoiding the necessity liner.

of dropping the wheels and axle, which operation involves Considerableloss of time and'delay. In assembling the liner, the operations abovementioned are simply reversed. I Y

This improvement can readily be applied to the existing driving-boxes oflocomotives and the like by simphproviding the necessary grooves forreceiving the liner-and the holding or clamping keys. This can be doneat small cost, in comparison with the saving of tiine' effect-ed by theuse of theimproved I claim as my invention:

1. The combination with a driving box having 'a bottom-openingfor theaxle and the lubricatingfcellar and provided in its face with an arcuategu deiway terminating v at said opening, a liner composed of sections'slidablelengthwis e' in said gn-ideway and re" movable therefromthrough said opening,

and means-for retaining the liner-sections in said guideway.

2. The combination with a 'driving box having a bottom-opening for theaxle and the lubricating cellar and provided in its face with an arcuateguideway terminating at said opening, a liner composed of sectionsslidable lengthwise in said guidcway and rea mo able therefrom only, bylongitudinal movement of the sections into said opening,

- and means for retaining said sections in the go idewa'y.

3. The "combination with a driving box having a bottom-opening for theaxle and the lubricating cellar and-provided in its face .with' anarcuate guideway terminating at said opening, a liner composed ofsections slidable lei'igthwiscin said guideway-and abutting attheirends,'an d clamping means at the ends of said guideway actingfluponthe lowermost liner-sections.

4. The combination with. a driving box 'havin a lmttonr-oienim for theaxlcand the lubricating, cellar and provided in its 'i'ace with anarcuate guide'way terminating at said opening, a liner composed ofsectionsslidable lengthwise in said guidcway, and transverse rr-tainingkeys extending across the ends of said gnidcway.

.3. The (-on'ibination with :1 having a bottom-opening fo lubricatingcellar and proviil driving box "he axle and it its outer side with an'undercut arcuatgroove,v the ends of said groove terminating at oppositetongue adapted ,to engage saidgrom'e, and
